Run to time, you find (5)
I believe the answer is:
trace
'find' is the definition.
(I've seen this before)
'run to time' is the wordplay.
'run' becomes 'race' (synonyms).
'to' means one lot of letters go next to another (I've seen this in other clues).
'time' becomes 't' (abbreviation).
'race' put after 't' is 'TRACE'.
'you' is the link.
(Other definitions for trace that I've seen before include "Follow step by step" , "Track; small quantity" , "Discover whereabouts" , "Copy by drawing on translucent paper" , "a piece of harness" .)
